A scientist wants to determine the best light wavelength for growing plants. He grows plants in four test groups as shown in the table below. What, if anything, was wrong with the experiment?

• He should only grow one plant in each group.
• He should only change the wavelength of light for each group.
• He should add a control group with a CO2 level of zero ppm and a light intensity of zero percent.
• There is nothing wrong with the experiment.

Based on the graphs below, assuming the y axis used the same values, which factor caused the highest rate of photosynthesis?

• light intensity
• CO2 concentration
• temperature
• Oxygen production

Which of the following is the best description of the process shown in the image below?

• Water, oxygen, and light are inputs while carbon dioxide and glucose are outputs.
• Water, oxygen, carbon dioxide, and light are inputs and glucose is the output.
• Water, carbon dioxide, and light are inputs while oxygen and glucose are outputs.
• Glucose, oxygen, and light are inputs while carbon dioxide and water are outputs.

What pigment produced in chloroplasts captures energy from the sun?

• ATP
• chlorophyll
• ribosomes
• DNA

Photosynthesis is the process

• by which animals convert food into energy from oxygen
• by which plants convert food to energy from oxygen
• by which animals make their own food from sunlight
• by which plants make their own food from carbon dioxide and water and sunlight
